Abstract

The invention relates to a baking oven for producing baked shaped bodies, comprising a baking line (6) that extends in one plane from its feeding station (4) to its discharge station (5). The baking tins consist of a lower baking plate (7) and an upper baking plate (9) placed on top of the lower baking plate. The baking tins are conveyed through the baking line (6) by a lower conveyor (2) that carries the lower baking plates (7) and that is arranged below the baking line plane. An upper conveyor (3) disposed above the baking line plane conveys the upper baking plates (9), in a suspended position, substantially horizontally aligned and with their baking surfaces (10) pointing downwards, through their trajectory that is disposed above the baking line plane. At the beginning of the baking line (6), the upper conveyor (3) places the substantially horizontally aligned upper baking plates (9) on the lower baking plates (7) to form the baking tins and removes them at the end of the baking line from the lower baking plates (7) to open the baking tins. The baking plates (7, 9) carried matching associated alignment elements (13, 14) that engage with each other when an upper baking plate (9) is placed on a lower baking plate (7) and they align the upper baking plate (9) while it is places on the subjacent lower baking plate (9).

Stand der TechnikState of the art
Aus der DE-PS 464 630 und der GB-PS 226 793 sind Waffelbackmaschinen zur Herstellung von flachen, rechteckigen Waffeln bekannt, die in den eine U-förmige Backstrecke durchlaufenden Waffelbackformen gebacken werden, die jeweils von einer oberen Backplatten und einer unteren Backplatte gebildet werden. Bei diesen Backmaschinen ist die Teig-Eingabestation an der Norderseite oberhalb der Waffel-Ausgabestation angeordnet und die entlang ihren beiden horizontalen Abschnitten jeweils von unten beheizte U-förmige Backstrecke führt von der Eingabestation durch das Innere der Backmaschine zur Ausgabestation.From DE-PS 464 630 and GB-PS 226 793 waffle baking machines for the production of flat, rectangular waffles are known which are baked in the waffle baking molds running through a U-shaped baking section, each of which is formed by an upper baking plate and a lower baking plate , In these baking machines, the dough input station is arranged on the north side above the waffle delivery station, and the U-shaped baking section, which is heated from below along its two horizontal sections, leads from the input station through the interior of the baking machine to the delivery station.
Die U-förmige Backstrecke erstreckt sich entlang der Außenseite einer endlosen, inneren Backplattenkette, deren Backplatten die unteren Backplatten der Waffelbackformen bilden. Die umlaufende Backplattenkette befördert ihre Backplatten von der oberen Eingabestation durch die U-förmige Backstrecke nach unten zur unteren Ausgabestation und von dieser über die an der Norderseite der Backmaschine angeordnete Umlenktrommel der Backplattenkette zurück nach oben zur oberen Eingabestation.The U-shaped baking section extends along the outside of an endless, inner baking plate chain, the baking plates of which form the lower baking plates of the waffle baking molds. The revolving baking plate chain conveys its baking plates from the upper input station down through the U-shaped baking section to the lower output station and from there via the deflection drum of the baking plate chain arranged on the north side of the baking machine back up to the upper input station.
Die U-förmige Backstrecke erstreckt sich auch entlang der U-förmigen Innenbahn einer äußeren, endlosen Backplattenkette, deren Backplatten die oberen Backplatten der Waffelbackformen bilden. Die umlaufende äußere Backplattenkette befördert ihre Backplatten in ihrer U-förmigen Innenbahn von der oberen Eingabestation entlang der Außenseite der inneren Backplattenkette und durch die U-förmige Backstrecke hindurch nach unten zur unteren Ausgabestation. Am unteren Ende der U-förmigen Backstrecke wird die äußere Backplattenkette über ihre an der Ausgabestation angeordnete, untere Umlenktrommel nach unten in ihre U-förmige Außenbahn umgelenkt. Diese führt unterhalb der Backstrek- ke entlang der Unterseite der Backmaschine nach hinten, entlang der Rückseite der Backmaschine nach oben und entlang der Oberseite der Backmaschine oberhalb der Backstrek- ke zurück nach vorne zum oberen Anfang der U-förmigen Backstrecke. An der Norderseite der Backmaschine wird die äußere Backplattenkette an ihrer oberhalb der Eingabestation angeordneten, oberen Umlenktrommel nach unten zum Beginn ihrer U-förmigen Innenbahn umgelenkt.The U-shaped baking section also extends along the U-shaped inner path of an outer, endless baking plate chain, the baking plates of which form the upper baking plates of the wafer baking molds. The revolving outer baking plate chain transports its baking plates in its U-shaped inner path from the upper input station along the outside of the inner baking plate chain and down through the U-shaped baking section to the lower output station. At the lower end of the U-shaped baking section, the outer baking plate chain is deflected downward into its U-shaped outer track via its lower deflection drum arranged at the dispensing station. This leads to the rear below the baking path along the underside of the baking machine, upwards along the back of the baking machine and along the top of the baking machine above the baking machine. ke back forward to the top of the U-shaped baking section. On the north side of the baking machine, the outer baking plate chain is deflected downwards at its upper deflection drum arranged above the input station to the start of its U-shaped inner path.
Bei diesen Backmaschinen wird jede Waffelbackform im oberen horizontalen Abschnitt der U-förmigen Backstrecke nur an ihrer unteren Backplatte beheizt. Beim Passieren der hinteren Umlenkung der Backstrecke wird die Waffelbackform auf den Kopf gestellt und im anschließenden unteren horizontalen Abschnitt der Backstrecke wird die Waffelbackform nur an ihrer, jetzt unten liegenden, oberen Backplatte beheizt.In these baking machines, each waffle baking pan in the upper horizontal section of the U-shaped baking section is only heated on its lower baking plate. When passing the rear deflection of the baking section, the waffle baking pan is turned upside down and in the subsequent lower horizontal section of the baking section, the waffle baking pan is heated only on its upper baking plate, which is now below.
Bei diesen Backmaschinen enthält die äußere Backplattenkette etwa doppelt so viele Backplatten wie die innere Backplattenkette. Bei der äußeren Backplattenkette kühlen die entlang der langen Außenbahn zurückgeführten Backplatten stärker ab, als die nur über die vordere Umlenktrommel zurückgeführten Backplatten der inneren Backplattenkette. In der U-förmigen Backstrecke werden die Backplatten der inneren Backplattenkette nur im oberen horizontalen Abschnitt der Backstrecke beheizt und die Backplatten der äußeren Backplattenkette werden nur im unteren horizontalen Abschnitt der Backstrecke beheizt.With these baking machines, the outer baking plate chain contains about twice as many baking plates as the inner baking plate chain. In the case of the outer baking plate chain, the baking plates returned along the long outer track cool more than the baking plates of the inner baking plate chain which are only returned via the front deflection drum. In the U-shaped baking section, the baking plates of the inner baking plate chain are only heated in the upper horizontal section of the baking section and the baking plates of the outer baking plate chain are only heated in the lower horizontal section of the baking section.
Der unterschiedliche Verlauf der beiden Backplattenketten und die auf unterschiedliche Teile der U-förmigen Backstrecke beschränkte Beheizung ihrer Backplatten führt zu großen Unterschieden bei den unvermeidlichen, wärmebedingten Längenänderungen der beiden Backplattenketten. Die unterschiedlichen, wärmebedingten Längenänderungen der beiden Backplattenketten können bei den Waffelbackformen zu einer unerwünschten, gegenseitigen Verschiebung ihrer Backplatten führen, wodurch das sich an der oberen Backplatte ausbildende Waffelmuster der Waffeloberseite gegenüber dem sich an der unteren Backplatte ausbildenden Waffelmuster der Waffelunterseite verschoben wird.The different course of the two baking plate chains and the heating of their baking plates limited to different parts of the U-shaped baking section leads to great differences in the inevitable, heat-related changes in length of the two baking plate chains. The different, heat-related changes in length of the two baking plate chains can lead to an undesirable, mutual displacement of their baking plates in the waffle baking molds, as a result of which the waffle pattern on the top of the waffle that forms on the upper baking plate is shifted compared to the waffle pattern on the underside of the waffle that forms on the lower baking plate.
Bei diesen Backmaschinen entstehen große Temperaturunterschiede bei den zur Eingabestation zurückgeführten oberen und unteren Backplatten der Waffelbackformen. Am Beginn der Backstrecke wird eine relativ stark abgekühlte, obere Backplatte zu einer weniger stark abgekühlten und bereits von unten beheizten, unteren Backplatte nach unten geklappt. Dabei kommt der sich auf der unteren Backplatte ausbreitende Waffelteig im vorderen Drittel der Backplatte etwas früher in Kontakt mit der etwas kühleren oberen Backplatte als im hinteren Drittel. Dies führt zu einer örtlich unterschiedlichen Erwärmung des zwischen den beiden Backplatten eingeschlossenen Waffelteiges. Dadurch kann eine unerwünschte, ungleichmäßige Färbung der Oberfläche der gebackenen Waffeln entstehen.These baking machines have large temperature differences in the upper and lower baking plates of the waffle baking molds that are returned to the input station. At the beginning of the baking section, a relatively strongly cooled upper baking plate is folded down to a less strongly cooled lower baking plate that has already been heated from below. The waffle dough spreading on the lower baking plate in the front third of the baking plate comes into contact with the somewhat cooler upper baking plate earlier than in the rear third. This leads to a locally different heating of the waffle dough enclosed between the two baking plates. This can result in an undesirable, uneven coloring of the surface of the baked waffles.
Bei diesen Backmaschinen verursacht die äußere Backplattenkette mit ihrer großen Län- ge und ihrer U-förmigen Außenbahn hohe Kosten für die zusätzlichen Backplatten und die zusätzlichen Umlenktrommeln an der Rückseite der Backmaschine. Der U-förmige Verlauf der Backstrecke macht eine Steigerung der Leistungsfähigkeit der Backmaschine durch eine deutliche Verlängerung ihrer Backstrecke unwirtschaftlich und erzeugt zusätzliche Probleme. Für eine Verlängerung der Backstrecke müßten bei der äußeren Backplattenkette stets doppelt so viele Backplatten hinzugefügt werden wie bei der inneren Backplattenkette. Dies würde sowohl bei den unvermeidlichen, wärmebedingten Längenänderungen der beiden Backplattenketten, als auch bei den Temperaturen der Backplatten am Beginn der Backstrecke jeweils die bereits bestehenden Unterschiede noch vergrößern. Bei einer Verlängerung der Backstrecke müßte auch die Umlaufgeschwindigkeit der beiden Backplattenketten vergrößert werden, damit auch bei verlängerter Backstrecke die für die Waffeln vorgesehene Backzeit mit der Durchlaufzeit der Waffelbackformen übereinstimmt. Die fünffache Umlenkung der äußeren Backplattenkette läßt aber nur eine begrenzte Erhöhung ihrer Umlaufgeschwindigkeit zu.With these baking machines, the outer baking plate chain with its large length ge and its U-shaped outer track high costs for the additional baking plates and the additional deflection drums on the back of the baking machine. The U-shaped course of the baking section makes an increase in the efficiency of the baking machine uneconomical by significantly extending its baking section and creates additional problems. To extend the baking distance, twice as many baking plates would always have to be added to the outer baking plate chain as to the inner baking plate chain. This would increase the already existing differences both in the inevitable, heat-related changes in length of the two baking plate chains and in the temperatures of the baking plates at the beginning of the baking section. If the baking section were to be extended, the speed of rotation of the two baking plate chains would also have to be increased so that the baking time provided for the wafers coincides with the throughput time of the waffle baking molds even with an extended baking section. The five-fold deflection of the outer baking plate chain allows only a limited increase in its rotational speed.
Aus der DE-OS 29 32 156 ist eine Anlage zum gleichzeitigen Herstellen von kreisförmigen, kleeblattförmigen und herzförmigen Oblaten in drei nebeneinander angeordneten Längsreihen bekannt. In dieser Anlage läuft ein als Schablone ausgebildetes, endloses Stahlband um, das in drei Längsreihen nebeneinander angeordnete, der jeweiligen Oblatenform entsprechende Ausstanzungen besitzt, in denen die Oblaten entstehen und haften bleiben, bis sie durch die von der hinteren Umlenktrommel des Stahlbandes abstehenden, der jeweiligen Oblatenform entsprechenden und in die Ausstanzungen des Stahlbandes eingreifenden Auswerfernocken aus den Ausstanzungen des Stahlbandes herausgedrückt werden.From DE-OS 29 32 156 a system for the simultaneous production of circular, cloverleaf and heart-shaped wafers in three adjacent longitudinal rows is known. In this system, an endless steel belt designed as a template circulates, which has cutouts arranged in three longitudinal rows next to each other and corresponding to the respective wafer shape, in which the wafers are formed and stick until they protrude from the respective rear of the steel belt Ejector cams corresponding to the wafer shape and engaging in the punched-out portions of the steel strip are pressed out of the punched-out portions of the steel strip.
In dieser Anlage läuft das Stahlband in seinem oberen, horizontalen Abschnitt zwischen zwei übereinander angeordneten Gehäusen hindurch, in denen jeweils drei endlose Formenketten nebeneinander angeordnet sind, die jeweils aus gelenkig miteinander verbundenen Backformteilen bestehen und oberhalb bzw. unterhalb einer Längsreihe von Ausstanzungen umlaufen. In den von dem Stahlband jeweils abgewandten, äußeren Abschnitten der Formenketten werden die Backformteile aufgeheizt. In den dem Stahlband jeweils zugewandten, inneren Abschnitten der Formenketten decken die Backformteile die Ausstanzungen der betreffenden Längsreihe an der Ober- bzw. Unterseite des Stahlbandes ab.In this system, the steel strip runs in its upper, horizontal section between two superimposed housings, in each of which three endless mold chains are arranged side by side, each consisting of articulated baking mold parts and circulating above or below a longitudinal row of punched-outs. The baking mold parts are heated in the outer sections of the mold chains facing away from the steel strip. In the inner sections of the mold chains facing the steel strip, the baking mold parts cover the punched-out sections of the relevant longitudinal row on the top and bottom of the steel strip.
In dieser Anlage werden die Teigportionen von stationären Dressierdüsen in die Ausstanzungen des umlaufenden Stahlbandes eingebracht, während die Ausstanzungen an ihren Unterseiten durch die heißen Backformteile der umlaufenden, unteren Formenketten abgedeckt sind und bevor die Ausstanzungen an ihren Oberseiten durch die heißen Backformteile der umlaufenden, oberen Formenketten abgedeckt werden. In den dann oben und unten jeweils durch heiße Backformteile abgedeckten Ausstanzungen entstehen die Oblaten, die mit ihren Rändern an den Rändern der Ausstanzungen haften bleiben, wenn die Backformteile von ihren Formenketten von der Oberseite bzw. Unterseite des Stahlbandes abgehoben werden. Das umlaufende Stahlband befördert die fertigen Oblaten, die in seinen Ausstanzungen haften geblieben sind, zu der an der hinteren Umlenktrommel des Stahlbandes angeordneten Ausgabestation, wo die Auswerfernocken in die Ausstanzungen eingreifen und die Oblaten aus den Ausstanzungen nach oben herausdrücken.In this system, the dough portions from stationary skin pass nozzles are introduced into the cut-outs of the surrounding steel belt, while the cut-outs on the undersides are made through the hot baking mold parts of the surrounding, lower mold chains are covered and before the cutouts on their tops are covered by the hot baking mold parts of the surrounding, upper mold chains. In the cutouts then covered at the top and bottom by hot baking mold parts, the wafers are formed which stick with their edges to the edges of the cutouts when the baking mold parts are lifted from their mold chains from the top or bottom of the steel band. The rotating steel belt conveys the finished wafers, which have stuck in its cutouts, to the output station located on the rear deflection drum of the steel belt, where the ejector cams engage in the cutouts and push the wafers upwards out of the cutouts.
Das mit den Ausstanzungen versehene Stahlband dient in dieser Anlage nicht nur als Schablone für die Herstellung der Oblaten, sondern auch als Transportband für die fertigen Oblaten, die in den Ausstanzungen des Stahlbandes verbleiben, während das Stahlband die Oblaten zuerst durch ein Dressierstation, in der Lebkuchenteigportionen auf den Oblaten abgesetzt werden, und dann durch eine Formstation transportiert, in der Formstempel auf die Lebkuchenteigportionen aufgedrückt werden, welche die Teigportionen in die gewünschte Form zu bringen und gleichzeitig über die jeweilige Oblate zu verteilen.In this system, the steel band with the punched-out not only serves as a template for the production of the wafers, but also as a conveyor belt for the finished wafers that remain in the punched-out sections of the steel band, while the steel band first passes the wafer through a skin-passing station in the gingerbread dough portions are placed on the wafers, and then transported through a forming station, in which form stamps are pressed onto the gingerbread dough portions, which bring the dough portions into the desired shape and at the same time distribute them over the respective wafers.
In dieser Anlage laufen die drei an der Oberseite des Stahlbandes nebeneinander angeordneten, oberen Formenketten gegensinnig zu den drei unterhalb des Stahlbandes nebeneinander angeordneten, unteren Formenketten um. Die einander zugewandten Abschnitte der oberen und unteren Formenketten sind jeweils durch das Stahlband von einander getrennt. Die Anlage weist drei nebeneinander angeordnete Längsreihen von Oblaten- Backformen auf, bei denen das Stahlband mit seinen Ausstanzungen den Hauptteil aller Oblaten-Backformen bildet, während die Backformteile jeder einzelnen Formenkette jeweils nur bei einer einzelnen Längsreihe von Oblaten-Backformen die oberen bzw. unteren Deckel der Oblaten -Backformen bilden.In this system, the three upper mold chains arranged side by side on the top of the steel belt run in opposite directions to the three lower mold chains arranged next to each other below the steel belt. The mutually facing sections of the upper and lower mold chains are each separated from one another by the steel band. The system has three longitudinal rows of wafer baking molds arranged side by side, in which the steel band with its punched-out forms the main part of all wafer baking molds, while the baking mold parts of each individual mold chain only have the upper and lower lids for a single longitudinal row of wafer baking molds of the wafer baking molds.
Zusammenfassung der Erfindung:Summary of the Invention:
Aufgabe der Erfindung ist es, einen verbesserten Backofen anzugeben, bei dem die Backplatten beim Bilden der Backformen gleichmäßig aufeinandergesetzt werden und der eine einfache Erhöhung seiner Leistungsfähigkeit durch Verlängerung seiner Backstrecke bei gleichzeitiger Erhöhung der Umlaufgeschwindigkeit der Backplatten ermöglicht.The object of the invention is to provide an improved oven in which the baking plates are placed evenly on top of one another when forming the baking molds and which enables a simple increase in its performance by lengthening its baking distance while simultaneously increasing the rotational speed of the baking plates.
Als Lösung wird ein Backofen zur Herstellung von gebackenen Formkörpern vorgeschlagen, welcher eine Eingabestation, eine Ausgabestation, einen langgestreckten Backraum, eine von der Eingabestation durch den Backraum zur Ausgabestation führende Backstrecke und in getrennten Umlaufbahnen in Längsrichtung des Backofens gegensinnig umlaufende, obere und untere Backplatten besitzt, die die Backstrecke in gleicher Richtung durchlaufen und dabei paarweise aufeinanderliegend die Backformen für die zu bak- kenden Formkörper bilden. Dieser Backofen ist erfindungsgemäß dadurch gekennzeichnet, daß eine von der Eingabestation bis zur Ausgabestation in einer Ebene verlaufende Backstrecke vorgesehen ist, daß die Backformen jeweils aus einer unteren Backplatte und aus einer auf deren Oberseite abgesetzten, oberen Backplatte bestehen, daß unterhalb der Backstreckenebene ein sich entlang der Umlaufbahn der unteren Backplatten erstreckender und die unteren Backplatten tragender, unterer Förderer angeordnet ist, der die Backformen von der Eingabestation durch die Backstrecke zur Ausgabestation transportiert, daß oberhalb der Backstreckenebene ein sich entlang der Umlaufbahn der oberen Backplatten erstreckender, oberer Förderer vorgesehen ist, der die oberen Backplatten jeweils hängend, im wesentlichen horizontal ausgerichtet und mit ihren Backflächen stets nach unten weisend transportiert, wobei der obere Förderer die im wesentlichen horizontal ausgerichteten oberen Backplatten am Beginn der Backstrecke zum Bilden der Backformen auf den unteren Backplatten absetzt und von den unteren Backplatten an der Ausgabestation zum Auflösen der Backformen wieder abhebt, und daß die oberen und unteren Backplatten einander gegenseitig zugeordnete Ausrichtelemente tragen, die beim Absetzen einer oberen Backplatte auf einer unteren Backplatte in Eingriff kommen und die obere Backplatte während ihres Absetzens auf die darunterliegende, untere Backplatte ausrichten.As a solution, an oven for the production of baked moldings is proposed, which has an input station, an output station, an elongated baking chamber, a baking path leading from the input station through the baking chamber to the output station, and in opposite directions in separate orbits in the longitudinal direction of the oven has circumferential, upper and lower baking plates which run through the baking section in the same direction and form the baking molds for the shaped articles to be baked in pairs lying one on top of the other. This oven is according to the invention characterized in that a baking path running from the input station to the output station is provided in a plane, that the baking molds each consist of a lower baking plate and an upper baking plate placed on the upper side thereof, that a along the baking path level the lower conveyor, which extends the orbit of the lower baking plates and which carries the lower baking plates and which transports the baking molds from the input station through the baking path to the output station, that above the baking path level there is an upper conveyor which extends along the orbit of the upper baking plates and which the upper baking plates each hanging, essentially horizontally aligned and always transported with their baking surfaces pointing downwards, the upper conveyor forming the substantially horizontally aligned upper baking plates at the beginning of the baking path n of the baking molds on the lower baking plates and lifts again from the lower baking plates at the dispensing station for dissolving the baking molds, and that the upper and lower baking plates carry mutually assigned alignment elements which come into engagement when a upper baking plate is placed on a lower baking plate and Align the upper baking plate with the lower baking plate underneath as it sets down.
Bei dem erfindungsgemäßen Backofen setzt der obere Förderer die von ihm hängend getragenen, oberen Backplatten am Beginn der Backstrecke auf den unteren Backplatten ab und läßt die auf den unteren Backplatten liegenden, oberen Backplatten los. Der untere Förderer transportiert die aus den unteren Backplatten und aus den auf diesen abgesetzten oberen Backplatten gebildeten Backformen durch die Backstrecke. Am Ende der Backstrecke übernimmt der obere Förderer die auf den unteren Backplatten abgesetzten, oberen Backplatten und hebt sie von den unteren Backplatten ab. Dabei werden die Backformen aufgelöst und die in ihnen gebackenen Formkörper werden aus den Backform ausgegeben bzw. entnommen. Vom Ende der Backstrecke weg transportiert der obere Förderer die oberen Backplatten jeweils im wesentlichen parallel zur Backstreckenebene ausgerichtet zurück zum Anfang der Backstrecke, wo er sie wieder auf den Backplatten des unteren Förderers absetzt und an diesen übergibt.In the oven according to the invention, the upper conveyor places the upper baking plates which it hangs on the lower baking plates at the beginning of the baking section and lets go of the upper baking plates lying on the lower baking plates. The lower conveyor transports the baking molds formed from the lower baking plates and from the upper baking plates placed on them through the baking path. At the end of the baking section, the upper conveyor takes over the upper baking plates placed on the lower baking plates and lifts them off the lower baking plates. The baking molds are dissolved and the molded bodies baked in them are discharged or removed from the baking mold. From the end of the baking section, the upper conveyor transports the upper baking plates, oriented essentially parallel to the baking section level, back to the beginning of the baking section, where it sets them down again on the baking plates of the lower conveyor and transfers them to the latter.
Bei dem erfindungsgemäßen Backofen werden die oberen Backplatten bei ihrer Übergabe an die Backplatten des unteren Förderers jeweils im wesentlichen parallel zur Backstreckenebene ausgerichtet auf die in der Backstreckenebene liegenden, unteren Backplat- ten abgesenkt. Dadurch wird bei jeder einzelnen Backform die nach unten weisende Backfläche der oberen Backplatte senkrecht zur Backstreckenebene auf die Oberseite der Teigbzw. Backmasse aufgesetzt, die auf der nach oben weisenden Backfläche der unteren Backplatte liegt. Beim Absenken der oberen Backplatte kommen deren Ausrichtelemente mit den Ausrichtelementen der darunterliegenden, unteren Backplatte in Eingriff. Die absinkende, obere Backplatte richtet sich während ihres Absinkens selbsttätig gegenüber der unteren Backplatte aus. Die vom oberen Förderer losgelassene, obere Backplatte liegt dann in der durch die Ausrichtelemente der beiden Backplatten bestimmten Position auf der unteren Backplatte auf. Dieser Ausrichtvorgang wird bei jeder einzelnen Backform von den Ausrichtelementen ihrer Backplatten gesteuert. Beim Absetzen der oberen Backplatten auf den unteren Backplatten werden durch den jeweiligen Ausrichtvorgang auch geringfügige Längsverschiebungen der oberen Backplatten gegenüber den unteren Backplatte ausgeglichen, wie sie z.B. durch unterschiedliche, wärmebedingte Längenänderungen der beiden Förderer verursacht werden können.In the oven according to the invention, the upper baking plates, when they are transferred to the baking plates of the lower conveyor, are aligned essentially parallel to the baking line level to the lower baking plate lying in the baking line level. ten lowered. As a result, the downward-facing baking surface of the upper baking plate is perpendicular to the baking stretch level on the top of the dough or with each individual baking pan. Place the baking mass on the upward-facing baking surface of the lower baking plate. When lowering the upper baking plate, its alignment elements come into engagement with the alignment elements of the lower baking plate underneath. The sinking, upper baking plate automatically aligns itself with the lower baking plate as it sinks. The upper baking plate released from the upper conveyor then lies on the lower baking plate in the position determined by the alignment elements of the two baking plates. This alignment process is controlled by the alignment elements of your baking plates for each individual baking pan. When the upper baking plates are placed on the lower baking plates, the respective alignment process also compensates for slight longitudinal displacements of the upper baking plates with respect to the lower baking plate, as can be caused, for example, by different, heat-related changes in length of the two conveyors.
Die erfindungsgemäße Ausbildung des Backofens erlaubt eine einfache Anpassung des Backofens an die jeweils gewünschte Leistung. Sowohl beim oberen Förderer als auch beim unteren Förderer kann die Anzahl der Backplatten durch lineares Verlängern des jeweiligen Förderers auf einfache Weise vermehrt und die Umlaufgeschwindigkeit der Backplatten an die verlängerte Backstrecke angepaßt werden, ohne dadurch zusätzliche Probleme zu verursachen.The design of the oven according to the invention allows the oven to be easily adapted to the desired output.

Die oberen Backplatten 9 werden vom oberen Förderer 3 am Beginn seines unteren Stranges auf den unteren Backplatten 7 abgesetzt und vom unteren Förderer 2 durch die Backstrecke 6 nach hinten zur Ausgabestation 5 transportiert. Nach der Ausgabestation 5 werden die oberen Backplatten 9 wieder vom oberen Förderer 3 übernommen, der sie in seinem unteren Strang zu seiner hinteren Umlenkung 11 befördert und über diese hinweg in seinen, oberhalb der Backstrecke 6 angeordneten, oberen Strang. In diesem befördert der obere Förderer 3 die oberen Backplatten 9 jeweils hängend nach vorne zu seiner vorderen UmlenkungThe upper baking plates 9 are arranged one behind the other along their orbit with their baking surfaces 10 facing downward in the longitudinal direction of the oven 1. The upper baking plates 9 are placed on the lower baking plates 7 by the upper conveyor 3 at the beginning of its lower strand and transported by the lower conveyor 2 through the baking section 6 back to the dispensing station 5. After the dispensing station 5, the upper baking plates 9 are again taken over by the upper conveyor 3, which conveys them in its lower strand to its rear deflection 11 and over it in its upper strand arranged above the baking path 6.

As a result, the mutual positions of the mutually facing baking surfaces 8, 10 of the two baking plates 7, 9 lying one above the other are determined independently of external influences.
Zum Herstellen der gebackenen Formkörper werden an der Eingabestation 4 des Backofens 1 über eine nicht dargestellte Beschickungsvorrichtung die für die Formkörper vorgesehenen Teigportionen in flüssiger Form oder als elastische, knetbare Teigstücke auf die Backflächen 8 der unteren Backplatten 7 aufgebracht. Beim Absetzen der oberen Backplatten 9 auf den unteren Backplatten 7 werden die Teigportionen in den dabei entstehenden und jeweils von den übereinander liegenden Backplatten 7, 9 gebildeten Backformen eingeschlossen. Die Teigportionen werden in den Backformen durch die Backstrecke 6 transportiert, wobei durch den Backprozeß aus den Teigportionen gebackene Formkörper entstehen, bei denen die Gestalt ihrer Ober- und Unterseiten durch die Backflächen der übe- reinanderliegenden Backplatten 7, 9 bestimmt werden. An der Ausgabestation 5 des Backofens 1 werden die oberen Backplatten 9 wieder vom unteren Strang des oberen Förderers 3 übernommen und von den unteren Backplatten 7 abgehoben.
